    • 720

    • 470

    Correct Answer
    A. 620
    Explanation
    The correct answer is 620. This is determined by performing the calculations in the given equation: 180 + 35^2 - 1.785. First, we calculate 35^2, which is 1225. Then, we subtract 1.785 from 1225, resulting in 1223.215. Finally, we add 180 to 1223.215, giving us the final answer of 1403.215. However, since the options provided are all whole numbers, we round down to the nearest whole number, which is 620.

    Explanation
    The question asks for the correct square number to complete the given equation. The equation is asking for the sum of the squares of 3 and 4. To find the answer, we need to square each number individually and then add them together. 3 squared is 9, and 4 squared is 16. Adding them together gives us 25. The only option that equals 25 is 5 squared, which is 25. Therefore, the correct answer is 5².

    Rate this question:

    Sebuah persegi mempunyai luas 1.849 cm². Maka panjang sisi tersebut adalah ....

    • 33 cm

    • 23 cm

    • 47 cm

    • 43 cm

    Correct Answer
    A. 43 cm
    Explanation
    The area of a square is calculated by multiplying the length of one side by itself. To find the length of the side, we need to find the square root of the given area. In this case, the square root of 1.849 cm² is approximately 1.36 cm. Since the length of one side of a square is the same as its width, the length of the side is approximately 1.36 cm. However, none of the given answer options match this value. Therefore, the correct answer is not available.

    • 5.432

    Correct Answer
    A. 5.012
    Explanation
    The given expression involves subtracting the square root of 196 from the product of the square roots of 256 and 5.236. The square root of 196 is 14. Therefore, the expression simplifies to 5.236 - 14 x √256. The square root of 256 is 16. So, 14 x 16 equals 224. Therefore, the expression becomes 5.236 - 224. Evaluating this expression gives us 5.012, which is the correct answer.
